Title: Servo control system with half-open control loop - uses error signal obtained by comparing actual value with reference value
Inventor: NISHIZAWA SHUNICHI
IPC: F15B9/09
Filed: 1973-12-05
Abstract: The servo valve takes the form of an overlapping servo valve and the input signal is supplied to the overlapping servo valve via an operational amplifier. This amplifier has such a response characteristic that a closed control loop is formed in the control range in which the actual value of the correcting element approaches the reference value with a delay, while an open control loop can be formed after the actual value has almost reached the reference value. When a heavy fast moving body is stopped, the generation of percussive force is minimised by the delay under the effect of the closed control loop.

Title: Selectively switching-off for shorted sections of HV network - uses operating section cct. breakers during network cct. breakers temporary tripping
Inventor: EGLI ERNST
IPC: H02H3/06
Filed: 1974-01-25
Abstract: The control system selectively switches off short circuited sections of a h.v. distribution network. The ring network two end transformers are coupled to busbars (5, 6) which are in turn coupled over two main circuit breakers (7, 8) to the network lines. Each section of line between junctions (9, 10, 11) is separated from these junctions by secondary circuit breakers (12 to 17). If a section of line is short circuited the two main breakers trip out. The secondary breakers (15, 16) in the shorted section open and the main breakers close, thus isolating the faulty section. If the secondary breakers fail to open, the main breakers close as before, the persisting short circuit current is detected and they trip out again, this time remaining open.

Title: Braking control for multi motor electric vehicle - has arcing protection on brake switch and regenerative braking
Inventor: DREISER LEO
IPC: B60L7/00
Filed: 1974-08-13
Abstract: The electric vehicle is fitted with regenerative braking on all its electric motors which are self energising when the speed control lever is released and the brake lever moved to braking. If the lever is returned to the unbraked position, with the vehicle still travelling at speed, then the induced voltage on the braking motors, which can be up to twice that of the supply, can lead to arcing accross the brake switch, and subsequent damage. The invention provides a failsafe motor connection so that when the brake lever is returned to the off position at least one of the motors has its field coils shorted out, before the braking force is fully removed.

Title: Thin thermoplastics sheets produced by calendering - with reserve material at roll gap continuously supplemented at edges
Inventor: BOTSCH D I GUNTHER
IPC: B29C43/24
Filed: 1974-10-25
Abstract: Thermoplastics sheets are mfd. by rolling with >=1 pair of calendering rolls in such a way that a continuous beading of the thermoplastics is maintained on the feed side of the roll gap, esp. of the last pair of rolls; matl. of the same compsn. and approx. the same degree of plasticisation is supplied to the two edges of the beading in this region. Pref. this is done by folding over or rolling in the edges of the thick sheet of matl. as it approaches the beading region. The pref. edge width over which this feed or folding-over of matl. takes place is is not >1/10 of the entire width of the sheet, or length of the beading. The effect of the additional feed or folding-back of matl. is to counteract the results of the continual outward spread of matl. at the roll gap and thus to minimise the effects of twist at the edge of the sheet; this leads to improved optical quality and generally to uniformity in the resultant rolled sheet.
